As shown in fig. 1, a method for generating a three-dimensional scene model of a railway line has the following main flows (steps S101 to S105):

step S101, acquiring task information for constructing a three-dimensional scene model of a railway line;

step S102, obtaining account information, an account model and GIS information corresponding to task information, wherein the account information comprises mileage information of a railway line three-dimensional scene model to be constructed and basic information of a plurality of devices;

the electronic equipment stores ledger information, ledger models and GIS information of a plurality of railway lines in advance.

The account standing information, account standing model and GIS information stored in the electronic device are described below:

the method comprises the following steps of (I) standing account information:

the standing book information can be input and obtained by a user, and can also be obtained by an operation and maintenance system, a detection system and a management system of a butt joint railway. The ledger information stored by the electronic device includes mileage information and a railway line name of each railway line, and basic information of various devices in each railway line, where the basic information includes a railway line to which the device belongs, a category, a mileage position in the railway line, a number, a name, a length (a device having a length, such as a bridge, a tunnel, and the like), a height, a structure type, a hole number, a span, and the like.

It should be noted that each railway line and each equipment are numbered according to the railway management regulations.

a power supply device: contact net, pillar, weight, compensation device, etc.;

electric service equipment: transponders, base stations, repeaters, etc.

(II) standing book model:

the electronic equipment is provided with a model base, the model base stores account models of most railway basic equipment, and a user can also import customized account models into the model base according to own needs, wherein the account models in the model base are dynamic, and standard account models with different sizes can be generated aiming at different account information, wherein the standard account models are the account models matched with a real scene.

The ledger model stored in the model library and the customized ledger model can be generated by using a three-dimensional model tool, such as Solidworks and BIM.

(III) GIS information:

the user can input the required GIS information to the electronic equipment, and when the GIS information is input, the information such as the railway line name in the standing book information, the line name used in the GIS, the longitude and latitude information of a starting station, an ending station, a station section, a section range, a map level and the like is input to the electronic equipment as the preprocessing information.

In this embodiment, a user inputs a name of a railway line of a three-dimensional scene model to be constructed through a mouse, a keyboard, a touch screen, and the like of an electronic device to generate task information for constructing the three-dimensional scene model of the railway line, where the task information includes the name of the railway line.

The user can also set the contents such as the three-dimensional scene name, the railway line name, the line type, the line mileage range, the ledger type related to the scene and the like in the task information in the modes of a mouse, a keyboard, a touch screen and the like of the electronic equipment.

The following respectively explains the name of the three-dimensional scene model, the name of the railway line, the line category, the range of the line mileage and the type of the ledger related to the scene:

name of three-dimensional scene model: and the name is used as the name generated by the construction of the three-dimensional scene model.

The name of the railway line: the railway line names constructed by the three-dimensional scene model need to correspond to the railway line names in the standing account information, and need to be mapped with the railway line names in the GIS information.

It is worth noting that in reality, the railway line names in the standing book information of the railway under the condition are possibly inconsistent with the railway line names in the GIS information, so that mapping needs to be performed in advance, and the possibility that the generation of the three-dimensional scene model fails due to the fact that the corresponding relation cannot be found is reduced.

Line classification: and setting the line type of the generated railway line, wherein the line type comprises bidirectional types, upstream types, downstream types and the like, and particularly, the set line corresponds to the line in the ledger information.

The range of the route mileage is as follows: the method comprises the steps of setting a mileage range for generating a three-dimensional scene of a corresponding line, and generating a three-dimensional scene model of one section of the railway line according to the set mileage, wherein the mileage range can be limited by a starting station and an end station.

The type of the machine account: the type of the ledger which needs to be generated in a correlated mode in the task information is selected, the type of the ledger which needs to be displayed in a scene can be selected according to the requirement condition, and unnecessary equipment does not need to be selected.

The electronic equipment acquires the name of the railway line in the task information, and acquires the standing book information, the standing book model and the GIS information corresponding to the railway line based on the name of the railway line, wherein the standing book model and the GIS information correspond to the standing book information.

After the electronic equipment obtains the standing book information, the standing book model and the GIS information, the data of the standing book information, the standing book model and the GIS information need to be verified, so that the possibility that the generated three-dimensional scene model is abnormal due to data errors or data loss in the standing book information is reduced.

The following description is made for ledger information verification, ledger model verification, and GIS information verification, respectively.

(1) Checking account information: and verifying whether the standing book information in the mileage range of the railway route required to be generated in the task information exists, whether the type of the standing book meets the requirement, and whether the key field is lost.

Whether the key field has a deficiency is described by taking a bridge as an example. For example, the bridge type, the bridge center mileage, the bridge full length, the start mileage, the end mileage, the number of bridge holes, the total bridge hole length, the hole span pattern, the curve radius, and the curve length are essential key fields for constructing a bridge model, and when obtaining the ledger information, it is necessary to check whether the ledger information includes the essential key fields.

(2) Checking the standing book model: and verifying whether the model corresponding to the related standing book information is missing or not and whether the model meets the modeling requirement or not.

(3) And (3) checking GIS information: and verifying whether the data in the railway route mileage range and the railway route mileage range related to the task information are complete or not and whether the data can cover the modeling area or not.

It should be noted that after the standing book information is successfully verified, the standing book model and the GIS information are verified, but the sequence of the standing book model and the GIS information verification is not limited.

It should be noted that, when checking the ledger information, a measurement unit needs to be checked, for example, the standard format of the mileage information of the railway line is kilometer, and when the measurement unit of the mileage information of the railway line acquired by the electronic device is meter, the measurement unit meter needs to be changed to kilometer, so that the measurement unit in the ledger information is managed in a uniform format.

Step S103, if the checking of the standing book information, the standing book model and the GIS information is successful, constructing a scene model of the railway route based on the mileage information, the basic information and the standing book model;

when the checking of the standing book information, the standing book model and the GIS information fails, the electronic equipment feeds back verification failure information to the user, and when the supplementary content and the correction content of the error information input by the user through a mouse, a keyboard, a touch screen and the like of the electronic equipment are received, the checking of the standing book information, the standing book model and the GIS information is carried out again.

When the checking of the standing book information, the standing book model and the GIS information is successful, in order to reduce the possibility that errors occur in a constructed three-dimensional scene due to the fact that data of the standing book information, the standing book model or the GIS information which are pre-stored in the electronic equipment are modified in the subsequent modeling process, the successfully verified standing book information, the standing book model or the GIS information are separately stored.

Specifically, the standing book information, the standing book model and the GIS information which are successfully verified are extracted; acquiring the successfully verified standing book information, the standing book model and the task identifier of the task information corresponding to the GIS information; and independently storing the extracted standing book information, the standing book model and the GIS information based on the task identifier.

The task identifier may be a name of the railway line, or may also be a number of the railway line, which is not specifically limited in this embodiment.

When a railway line scene model is established based on successfully verified ledger information, ledger models and GIS information, a railway line needs to be divided into a plurality of station intervals, and the scene model is established by taking the station intervals as the minimum unit.

The following first explains the division of station sections:

after the electronic equipment acquires the name of the railway route, acquiring a plurality of stations in the railway route; the railway route is divided into a plurality of station sections based on a plurality of stations, wherein two adjacent stations and the railway route between the two adjacent stations form one station section.

For example, the name of a railway route needing to construct the three-dimensional scene model is a, stations contained in the railway route are b, c and d, and then the railway route between the station b and the station c and the railway route between the station b and the station c are divided into a station section; and dividing the railway routes between the station c and the station d and between the station c and the station d into a station section.

The following description will be given by taking the construction of a scene model of one station section as an example:

specifically, a standing book model matched with the type of the standing book is selected; adjusting the size of the selected standing book model based on the parameter information to obtain a standard standing book model; constructing a railway route of a scene model based on the mileage information and the plurality of stations; and setting each standard standing book model on a position corresponding to the railway route of the scene model based on the mileage position information of the equipment.

In this embodiment, a steel rail model is constructed as an example, the type of a steel rail, the length of a single steel rail, the laying length, the starting mileage and the ending mileage information of the steel rail are obtained based on the steel rail ledger information, and a scene model is constructed for the steel rail based on the type of the steel rail, the length of the single steel rail, the laying length, the starting mileage and the ending mileage information of the steel rail.

Firstly, selecting an account standing model corresponding to the type of the steel rail from the account standing models, placing the account standing models of the steel rail according to a straight line according to the laying length to obtain two parallel rails, and setting the width of the parallel rails according to the standard gauge width 1435 mm.

The ledger information of the steel rail includes information on the position of the corresponding mileage in the corresponding railway line, and the parameter information includes information on the length of the equipment (equipment having a length, such as a bridge or a tunnel), the height, the structure type, the number of holes, the span, and the like.

And correcting the left and right curves of the steel rail according to curve account information of the railway line, wherein the curve account information records the bending information of the railway line, and the bending information comprises information such as starting mileage, ending mileage, curve radius, starting and slowing length, and ending and slowing length of the curve. The steel rail is corrected through the curved ledger information, and at the moment, the steel rail is not a straight line any more, but the steel rail is the same as the steel rail with different curvatures in different areas in a real scene.

And finally, according to the ledger information of the gradient, correcting the height of the steel rail in the horizontal direction, wherein the gradient reflects the condition that the line is ascending, descending or horizontally advancing, and at the moment, a steel rail model in the scene model is constructed.

Because the standing book model is constructed in a segmented manner according to the standing book information, a plurality of standard standing book models of the same type need to be connected in series according to the mileage information, and the standing book models of different types are combined or placed to obtain the scene model of the whole railway line.

The following description is directed to the cascading of ledger models of the same ledger type:

table 1 shows ledger information of the steel rail.

TABLE 1

Numbering	Starting mileage/km	End point mileage/kilometer	Rail type	Steel grade	Length of single rail/meter
						1	-2.309	-1.207	60 in	U75V	25
2	-2.219	-1.808	50 in	U74V	25
						3	-1.838	-1.338	60 in	U75V	100

As shown in table 1, the ledger information of the steel rail includes starting-point mileage and ending-point mileage information laid corresponding to the type of the steel rail, and since the types of the steel rails are different, the three-dimensional scene is constructed by segment modeling according to the starting-point mileage, the ending-point mileage and the type of the steel rail, so that each ledger model is an independent model, and therefore ledger models of the same type need to be connected in series to form a station section, and a plurality of station section ends are connected together to form a three-dimensional scene model of a complete line.

The following describes the serial connection of ledger models of the same ledger type for the same station interval:

for example, the starting mileage of the a-type steel rail is 100 meters, the ending mileage of the a-type steel rail is 200 meters, the length of a single steel rail is 25 meters, 4 a-type steel rails are needed, 4 a-type steel rails are laid between 100 and 200 meters in kilometers, and the 4 steel rails are connected in series.

The following first explains the series connection of ledger models of the same ledger type in different station intervals:

for example, if the starting distance of the b-type rail in the station section a is 100 meters and the ending distance thereof is 200 meters, and the starting distance of the b-type rail in the station section c is 200 meters and the ending distance thereof is 300 meters, the b-type rail in the station section a and the rail in the station section c are connected in series.

It should be noted that different types of steel rails belong to the same steel rail category, and the ledger models can be connected in series according to the same ledger type.

Specifically, the serial connection of the ledger models may be performed after the scene model is created, or may be performed before the ledger models are corrected by the ledger information of the curve and the ledger information of the slope, which is not specifically limited.

The following description is directed to combining or placing ledger models of different ledger types:

as shown in fig. 2, taking a ballast track as an example for explanation, the electronic device stores a preset position relationship, where the preset relationship is to place a sleeper on a ballast track bed and place a steel rail on the sleeper.

For example, the data in the ledger information is that 0-5 kilometers are straight rails, 0-5 kilometers are sleepers, 0-5 kilometers are ballast tracks, models of different types of ledgers are placed, grouped and built into a ballast track as shown in fig. 2 through a preset position relation, so that a station interval is formed, and the ledger models of different types form a scene model so as to achieve the purpose that the ledger models are displayed according to a real scene.

Step S104, correcting the trend of the railway line in the scene model based on GIS information;

since the ledger information does not include information such as direction, coordinates, longitude and latitude, the advancing direction and position of the railway line of the scene model are different from the real situation, and at this time, the trend of the railway line of the scene model needs to be corrected through the GIS information.

As shown in fig. 3, the method specifically includes the following steps (step S1041 to step S1046):

step S1041, obtaining a plurality of station sections in a railway route of a scene model;

step S1042, acquiring a GIS map corresponding to each station interval;

step S1043, acquiring a starting point station and an end point station in each GIS map, and marking a railway route between the starting point station and the end point station to obtain a marked route;

the marking mode can mark red on the railway route, and can also thicken the railway route, but is not limited to the marking mode.

Step S1044, taking the marked GIS map as a base map of a corresponding station interval;

step S1045, respectively corresponding a starting point station and an end point station of the station section to a starting point station and an end point station of the GIS map;

and step S1046, correcting the railway route in the station section based on the marked route.

In this embodiment, a steel rail is taken as an example, the position of the steel rail in the scene model is adjusted according to the trend of the railway line in the GIS map, so that the laying route of the steel rail in the scene model is consistent with the trend of the railway line in the GIS map, and the positions of other standard ledger models are adjusted according to the data of the ledger information.

The marked GIS map can be projected into the scene model, stations in the scene model correspond to a starting point station and an end point station in the GIS map, for example, the GIS map comprises a station a and a station b, the station a in the scene model corresponds to the station a in the GIS map, the station b in the scene model corresponds to the station b in the GIS map, and at the moment, the position of a standard ledger model in the scene model is adjusted according to the railway lines marked in the GIS map until the trend of the railway lines in the scene model is consistent with the trend of the railway lines in the GIS.

And the top view of the scene model can be acquired, the top view of the scene model is overlapped with the GIS map, the transparency of the top view of the scene model is adjusted, the station of the top view in the scene model corresponds to the starting point station and the end point station in the GIS map, and the position of the standard ledger model in the scene model is adjusted according to the railway line trend in the GIS map and the railway line trend in the top view of the scene model until the trend of the railway line in the scene model is consistent with the trend of the railway line in the GIS.

And S105, fusing the corrected scene model and satellite geographic information corresponding to the GIS information to obtain a three-dimensional scene model of the railway route.

Specifically, the gradient of the railway line in the GIS map is adjusted based on the gradient of the railway line of the scene model, so that the gradient of the railway line in the GIS map is consistent with the gradient of the railway line of the scene model; and fusing the adjusted GIS map and the corrected scene model.

In this embodiment, the gradient of the railway line of the GIS map is adjusted according to the gradient of the railway line in the ledger information, and the adjusted GIS map is consistent with the gradient of the railway line in the scene model, instead of being a plane map, so as to generate the three-dimensional scene model.

After the three-dimensional scene model is generated, the electronic equipment previews, displays, releases and packages the three-dimensional scene model, and the packaged three-dimensional scene model can be used by other systems.
